IMPROVEMENT IN wlNDNuLLs.

Specification forming partworf Letters Patent No.)v 156,316, datedOctober 27, 1874; applicationvled Y f Y March 17,1874.

To all whom it may concern:

Be it known that we, UHIPMAN W. SHoLEs and HENRY C. KELLY, of Morrison,in the county of Whitesides and State of Illinois,

have invented certain Improvements in Windmills, of which the followingis a specification:

This invention relates to that class of wind-v mills Yin which the Wheeland tail can turn to some extent independently of each other, and are sodisposed with reference to each other andintermediate devices thatwhenever the strength of the wind exceeds that required to turn theWheel at the proposed maximum speed, the Wheel Will first automaticallyturn the tail, which then in turn will throw the Wheel more or less outof twind. My improvement consists mainly in the combination of a tailand Wheel supporting frame, turning separately in one direction on acommon axis, with a horizontally-sliding wheel carrying back and forthwith' it a sliding rod which bears with its outer end against aprojecting arm on the tail or its hub, and turns such tail against theWeight of a counterpoise to throw the wheel out of Wind in the mannerheretofore stated whenever the wind becomes too strong.

In the annexed drawings', Figure 1 is a vertical longitudinal section ofmy improved windmill. Fig. 2 is a plan view of the same. Fig. 3 yis anelevation of the hubs of the Wheel frame and tail and their connectingdevices.

The same letters of reference are used in all the f gures in thedesignation of identical parts.

The wings of the wheel A radiate from a central hub, A', bymeans ofwhich itis mounted upon the horizontal shaft B, turning in bearings onthe frame C. The latter terminates in a downwardly-projecting tubularhub, G1, which passes through ,the tubular hub D1 of the tail D,supported in vertical bearings on the main frame or post. The upper endof the hub C1 is provided with a fixed laterally-projecting arm, G2,which, when brought up angles to the tail under all ordinarycircumstances. The rope E1 is also fastened to a hinged arm or lever, E2on the tail, by means of which the weight E may be lifted more orv lessto cause the wheel to be turned by the' wind, so as to stand obliquelywith reference to the tail, and, consequently, the direction of thewind. The wheel is arranged to slide on its shaft the moment the windbecomes stronger than required to turn the mill at the highest desirablevelocity, and to turn the tail, in doing which it is itselfthrown moreor less out of wind. To this end, a collar, a, on its hub, entersbetween the forks projecting laterally from a bar, F, which, beingsupported in lugs on the frame C, bears with its outer end against a ribon bracket D2 on the tail-hub, all as clearly exhibited in Fig. 2. Theweight E is of suchV proportion that it will hold the parts in thepositions exhibited in Fig. 2 until the Wheel reaches its maximum speed.Passing that, the resistance of the weight is overcome, and the Wheelslidinginward on its shaft turns, through the slide-bar F, the tail atan oblique angle to it, and the tail again immediately adjusting itselfto the wind turns the wheel out of wind. In the example illustrated boththe wheel and shaft are capable of longitudinal or sliding movement,Vthe wheel sliding separately until it brings up against the collar b,after which both slide together. It is evident, however, that the wheelmay be made fast on the shaft and both'slid together. The extent ofmovement should be such that the slide-bar will remain in contact withthe bracket until the wheel arrives at an angle of, say, forty-fivedegrees to the tail; but the wheel may be turned until it stands inaplane parallel to the tail. The wheel-shaft has a cra k at its extremeend, which is connected to the slotted cross-head of the rod G, whichpasses through the hub C1, and may' be hitched to the plunger of a pump.The aperture through the hub O1 is flat or angular, and the rod Gis ofcorresponding form in cross-section, so that its cross-head will alwaysremain in proper' position relatively to the crank under varyingpositions of the wheel. The lower ends of the hubs G1 and D1 are,respectively, provided with a fixed arm, C3, and fixed brackets D1. andby means of a rope, H, fastened with en end to the arm (J3, and movingover sheaves on the brackets D3. By pulling on the rope H the Wheel maybe thrown more or less out of wind to regulate its velocity.

We hereby disclaim the invention of Sylvester E. Ament for animprovement in windmills, tiled April 2l, 1873, in the United StatesPatent Olice.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. The wheel A A', sliding shaft B, colla-r a, sliding bifurcated bar F,frame C, and tubular hubs G1 and D1, having the ribbed bracket D2, incombination, substantially as'and for the purpose specified.

2. The arm C, rope El, weight E, tail D,

yand lever E2, in combination with the wheel nesses. v
